Victorian Premier urges community to unite

Victorian Premier Denis Napthine said it was important that the incident did not divide the community.

"Let me make it very, very clear, one of the greatest strengths, one of the greatest assets we have here in Victoria is our harmonious, diverse, multi cultural, multi-faith community," Dr Napthine said.

"We need to preserve and protect that. We need to enhance and build on that.

"We shouldn't let a single incident divide that. We need to show each other respect, be tolerant and remain united."

He said authorities were working together to ensure the safety of the community.

"It is imperative that we do all that we can to reassure all members of the Victorian community that everything is being done to protect our safety and making sure that our community continues to work together as a whole Victorian community," Dr Napthine said.

Islamic leaders criticise police investigation

Leaders of Melbourne's Islamic community have criticised police over their investigation into the fatal shooting.

Gaith Krayem from the Islamic Council of Victoria said police were quick to jump to conclusions.

"I was disappointed with the immediate press conference police held last night. It was held three hours after the event, and they drew conclusions immediately," Mr Krayem said.

"There needs to be a proper process as there always should be when police are involved in a fatality."

What we do know is that there's an 18-year-old young man who is dead this morning, there are two police officers in hospital, there is a family who is grieving.

Mr Krayen said the public needed to reserve their judgement until a full and objective investigation has taken place.

"Immediately, individuals such as this unfortunately are given these labels of a radical, or a terrorist, or an extremist," he said.

"Unfortunately, because of the environment we're in, as soon as you label somebody like that, people don't want to then question what occurred.

"We don't know really what happened when this young man arrived at the police station.

"What we do know is that there's an 18-year-old young man who is dead this morning, there are two police officers in hospital, there is a family who is grieving."
